  • The Long-Term Impact of Adverse Childhood Experiences on Cognitive Flexibility and Anxiety

    Recent research has shed light on the lasting effects of adverse childhood experiences (ACEs) on cognitive function and mental health in adulthood. Two studies by Kalia and colleagues provide compelling evidence for the relationship between early life adversity and reduced cognitive flexibility, as well as increased vulnerability to anxiety during stressful events.

    Study 1: ACEs and Cognitive Flexibility

    In their 2021 study, Kalia, Knauft, and Hayatbini examined the relationship between ACEs and cognitive flexibility in both college students and community adults. Using the Wisconsin Card Sorting Test (WCST) to measure cognitive flexibility, they found:

    1. Higher ACE scores were associated with fewer completed categories on the WCST in both groups.

    2. The negative correlation between ACEs and cognitive flexibility persisted even after controlling for factors like age, gender, and race/ethnicity.

    3. Individuals with more ACEs reported higher levels of perceived chronic stress.

    4. Age independently predicted reduced cognitive flexibility in the adult sample.

    These findings suggest that early life adversity may have enduring effects on cognitive flexibility, an important executive function associated with positive outcomes in adulthood.


    Study 2: Childhood Maltreatment, Cognitive Flexibility, and COVID-19 Anxiety

    In a 2020 study, Kalia and colleagues explored the relationships between ACEs, cognitive flexibility, perceived threat from COVID-19, and state anxiety. They surveyed 356 U.S. adults during the early stages of the COVID-19 pandemic and found:

    1. Childhood maltreatment was associated with increased perceived threat from COVID-19 and higher levels of state anxiety.

    2. Cognitive flexibility, particularly the ability to perceive difficult situations as controllable, mediated the relationship between childhood maltreatment and anxiety.

    3. Both perceived threat from COVID-19 and reduced cognitive flexibility explained the link between childhood maltreatment and increased anxiety levels.

    4. Household dysfunction, another form of ACEs, did not show the same relationships with perceived threat and anxiety as maltreatment did.

    This study suggests that individuals who experienced maltreatment in childhood may be more vulnerable to anxiety during stressful events like the COVID-19 pandemic, partly due to their tendency to perceive greater threat from environmental stressors and reduced ability to flexibly appraise challenges.

    Implications and Conclusion

    Together, these studies highlight the importance of addressing childhood adversity and its potential long-term impacts on cognitive functioning and mental health. The research underscores the need for targeted support for individuals with a history of maltreatment, particularly during times of widespread stress. Enhancing cognitive flexibility in adults who experienced childhood maltreatment could be a promising avenue for treatment programs aimed at reducing anxiety and improving overall well-being.

  • Unraveling the Complexities of Orthorexia Nervosa: My Doctoral Journey

    As I reflect on my doctoral dissertation, I'm excited to share with you the key insights from my research into orthorexia nervosa, cognitive flexibility, and distress tolerance. This work represents a significant contribution to our understanding of this emerging eating disorder and its relationship with important cognitive and emotional processes.

    The Research Journey

    My dissertation comprised three cross-sectional studies, each building upon the last to create a comprehensive picture of orthorexia nervosa and its associated factors:

    1. Study 1: State Cognitive Flexibility and Orthorexia Nervosa

       - Examined the relationship between state cognitive flexibility (measured by the Cognitive Flexibility Inventory) and orthorexia nervosa symptoms during the COVID-19 pandemic.

       - Key Finding: Lower perceived ability to control difficult situations was associated with higher orthorexia nervosa symptoms. Surprisingly, a greater ability to generate alternative solutions was linked to increased symptoms, possibly due to the unique context of the pandemic.

    2. Study 2: Trait Cognitive Flexibility and Orthorexia Nervosa

       - Investigated trait cognitive flexibility using the Wisconsin Card Sorting Test in relation to orthorexia nervosa symptoms.

       - Key Finding: Cognitive inflexibility (measured by perseverative errors) was associated with positive feelings and increased knowledge about restrictive eating habits. However, cognitive flexibility (measured by completed categories) was linked to increased knowledge and greater perception of problems related to orthorexia.

    3. Study 3: Distress Tolerance, Cognitive Flexibility, and Orthorexia Nervosa

       - Explored the relationships between distress tolerance, cognitive flexibility, and orthorexia nervosa symptoms.

       - Key Finding: Lower distress tolerance was associated with higher orthorexia nervosa symptoms. The control aspect of cognitive flexibility served as a protective factor, especially when combined with higher distress tolerance. Conversely, the alternatives aspect of cognitive flexibility was a risk factor when combined with lower distress tolerance.

    Key Takeaways

    1. Cognitive Flexibility is Multifaceted: My research highlighted that different aspects of cognitive flexibility (control vs. alternatives) can have varying impacts on orthorexia nervosa symptoms.

    2. Context Matters: The COVID-19 pandemic significantly influenced the relationship between cognitive flexibility and orthorexia nervosa symptoms, emphasizing the importance of considering environmental factors in eating disorder research.

    3. Distress Tolerance is Crucial: The ability to tolerate negative emotional states plays a significant role in the development and maintenance of orthorexia nervosa symptoms.

    4. Complex Interplay: The relationships between cognitive flexibility, distress tolerance, and orthorexia nervosa are intricate and sometimes counterintuitive, highlighting the need for nuanced approaches in both research and clinical practice.

    Implications and Future Directions

    My research suggests that interventions targeting both cognitive flexibility and distress tolerance may be beneficial for individuals with orthorexia nervosa. Future studies should explore these relationships in clinical populations and use a combination of self-report and performance-based measures to capture the full complexity of cognitive flexibility.

    As we continue to unravel the complexities of orthorexia nervosa, it's clear that a multifaceted approach considering cognitive, emotional, and environmental factors is essential. I'm excited to see how this research will contribute to better understanding and treatment of orthorexia nervosa in the future.



  • Unveiling the Hidden Burden: Subclinical Body Dysmorphic Disorder in College Students

    As part of my Master's thesis, I conducted groundbreaking research on Subclinical Body Dysmorphic Disorder (SC-BDD) in college students. This study is the first of its kind to examine neuropsychological correlates of SC-BDD while addressing related clinical factors and severity of psychopathological symptoms. Here are the key findings and their implications:

    Key Findings:

    1. Intact Cognitive Functions: Contrary to our initial hypotheses, SC-BDD participants showed intact cognitive functions across all measured domains, including memory, visuospatial function, and verbal function.

    2. Significant Psychopathological Burden: Despite normal cognitive performance, SC-BDD participants exhibited clinically significant moderate levels of anxiety, depression, and stress symptoms.

    3. Predictors of SC-BDD: Depression emerged as a strong predictor of SC-BDD, followed by anxiety. Together, these factors explained about half of the variance in SC-BDD symptoms.

    4. Academic Performance: Interestingly, SC-BDD participants maintained intact academic performance despite their psychological burden.

    Implications:

    1. Hidden Struggles: The study reveals that college students with SC-BDD may be suffering silently. Their intact cognitive and academic performance might mask significant psychological distress.

    2. Need for Awareness: There's a crucial need for increased awareness about body image concerns and SC-BDD symptoms among college students and university health services.

    3. Screening and Support: Universities should consider incorporating screenings for body image concerns and related psychological symptoms into their health services.

    4. Early Intervention: Given the link between SC-BDD, depression, and anxiety, early identification and intervention could be key in preventing more severe outcomes.

    This research underscores the importance of looking beyond academic performance when assessing student well-being. It calls for a more holistic approach to student mental health, one that recognizes the complex interplay between body image concerns, psychological distress, and cognitive functioning.

    As we move forward, it's crucial that we continue to investigate these hidden struggles and develop targeted interventions to support students dealing with SC-BDD and related concerns.
